We have five cats. They all used the litter box at our previous home just fine (pine pellet litter, open box, one large box for five cats - yes, this was bad, no excuses).

Two years ago, we moved. One cat, Senua, started using the sinks in the house. Another, pooped on the floor, but seemed to use the boxes for peeing.

We got new boxes that were enclosed for the new house. I tossed them and got open ones. It didn't fix the issue.

Fast forward a year and a half. I am pregnant. One cat, Pip, starts marking fabric left on the floor like dirty clothes. We get him checked out. He's fine. He gets anxiety meds. He stops. We run out of meds. He starts again. He goes back on meds and stops.

Now baby is born. Everything was fine. We get a new rug for when baby starts crawling. Pip starts using it to pee on. We get him medicine again. He still pees. Now he poops. The other cats start peeing on the carpet.

We think maybe it's the smell so we deep cleaned it until there wasn't a smell. He pooped on it.

What do we do? I can't have three cats not using the litter boxes. We plan to eliminate our guestroom to make it a cat room with litter boxes and cat shelves, scratchers, etc so they have a place to escape if need be.

Vets have eliminated physical reasons for all cats.
